What is the solution to the equation 2𝑥+3=7?
Correct!
Wrong!
Subtract 3 from both sides to get 2𝑥=4, then divide both sides by 2 to get 𝑥=2
Simplify the expression (3𝑥2𝑦)⋅(2𝑥𝑦3)
Correct!
Wrong!
Multiply the coefficients (3 and 2) to get 6, then add the exponents of the same bases: x2+1 and 𝑦1+3 to get 6𝑥3𝑦4
What is the factorization of the quadratic expression x2-5x+6?
Correct!
Wrong!
Find two numbers that multiply to 6 and add to -5; they are -2 and -3.
Solve the inequality 3𝑥−4<2𝑥+5
Correct!
Wrong!
Subtract 2𝑥 from both sides to get x−4<5, then add 4 to both sides to get x<9.
If 𝑓 (𝑥) =2𝑥2−3𝑥+4, what is 𝑓 (−1)?
Correct!
Wrong!
Substitute −1 for x in the function: 𝑓 (−1) =2 (−1)2−3 (−1) +4=2 (1) +3 +4 =5.
